Gas shut-off notices sent by mistake

Utility officials say they don't know how many people were affected by the "mechanical error," or what caused it.

The notices warned recipients that they would be disconnected because they had ignored repeated contacts about a federally required safety inspection. But spokeswoman Elizabeth Castro said if customers have not received several letters and phone calls, they can ignore the notice.

Peoples Energy can legally disconnect service between Dec. 1 and March 31 only for reasons of safety or theft.
